IMPROVEMENT IN STOVE-DAMPERS.

Thefichedule referred to in these Letters Patent and maldng part of thesame.

To all whom it may concern.-

Be itknowu that I, Ennns'r Lonsnnn, of La Porte, in the county of LaPorte and State of Indiana, have invented certain Improvements inDampers for Stoves and I dohereby declare that the following is a full,clear, and exact description thereof, reference being bad to the annexeddrawing making part of this specification, in which- Figure 1 is acentral vertical section of my improved damper as applied to aparlor-stove.

'Figure 2 is a side elevation of the device without the cover 01' doorand register.

Figure 3 is a side view of the register.

Figure 4 is a front view.

Figure 5 shows the side opening into the stove.

Figured is avertical transverse section.

- The same letters of reference are used in all the figures in thedesignation of identical parts.

This invention, relating to an illuminating damper for stoves, consistsin the combination of a short tube fastened by a flange to the casing ofthe stove, projecting through or surrounding an aperture therein,

with another short tube, somewhat longer and of greater diameter, which,surrounding it, is closed at the outer end by an illuminating door orcover, and has a series of openings in the upper portion of its shellfor the admission of air, the draught being regulated by a circularregister.

To enable those skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

The interior smaller tube A of the damper has, like the interior andlarger one, B, a circumferential flange for convenience in securing .itto the stove, from which it projects, as seen in the drawing, surroundedby the The smaller one is open at both ends, and its shell is providedwith series of perforations at short intervals to admit the air in finejets at those points.

Its outer end has an upturned lip, a, which extends about half-wayaround it, being widest at the bottom of the tube, and tapering off fromthat point toward each side, as best seen in fig. 5. This lip serves asa spark-arrester, causing the cinders to fall to the bottom of the tubeto be returned into the stove.

The tube B has several large openings, B, formed in its shell at thesides and on top, the lower portion remaining solid to catch sparkspassing entirely through v the inner tube.-

The draught of air through these openings is regulated by a circularregister, 0, which isnicely fitted on the tube B, and can be turned by aknob, c, to make, its apertures, or the intervening solid portions,regis-' ter with the openings 13, as required.

The forward or outer end of the tube 13 is closed by a door or cover,which consists of an annular rim, D, the opening of which is closed byapiece of mica, D, protected on the outside by a perforated sheet of tinor fine wire-cloth, so that the light of the'fire may always shinethrough it.

The rim of the cover may be of any ornamental design, and. is providedwith slots for the purpose of booking it onto projections of the tube'B.It ma} thus be easily removed to kindle a fire or poke it.

What I claim as my invention, and desire to secure by Letters Patent,is-- 1. The combination of the tube A surrounding slotted tube B closedat the outer end, and register 0, substantially as and for the purposeset forth.

2. The tube A constructed with an upturned lip, a, substantially as andfor the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribingwitnesses.
